HMX Jammy vs. Gazzew U4
An in-depth look at the HMX Jammy and the Gazzew U4 switches—which one is the best fit for you?
Overview
When it comes to mechanical keyboard switches, the HMX Jammy and the Gazzew U4 offer distinctive typing experiences for enthusiasts seeking a customized setup. The Jammy, a linear switch, boasts a softer nylon housing and medium weight that delivers a muted yet deeply satisfying typing experience. On the other hand, the U4, a tactile switch, features a sharp and exhilarating tactile bump, along with a plush, felt-like bottom-out sensation. Additionally, the U4's sound profile is whisper quiet, making it an ideal choice for those who prefer a low-pitched and sharp typing sound. Both switches offer unique benefits, making them suitable for different preferences and typing styles. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
The housing materials of the HMX Jammy and Gazzew U4 both bring unique sound profiles to their switches due to their softness and ability to absorb sound. The nylon top housing of the Jammy creates a deeper and fuller sound profile, while the U4's proprietary Gazzew blend top housing delivers a rich and deep sound. In terms of bottom housing, the Jammy's nylon material also creates a duller and rounder sound profile, similar to the U4's Gazzew blend bottom housing which produces a rich and deep sound. Overall, both switches offer a similar typing experience in terms of sound due to their soft housing materials.
However, the Jammy and U4 switches may offer variations in feel and sound when comparing the top and bottom housing materials. The bottom housing material of a switch typically impacts the bottom-out sound and feel, while the top housing has more of an influence on the sound when a key is released. This means that despite the similar sound profiles provided by the nylon and Gazzew blend materials, users may notice subtle differences in the typing experience between the two switches. The differences in material properties may affect the overall feel and sound of the switches during use.
In conclusion, while both the HMX Jammy and Gazzew U4 switches utilize soft housing materials to create rich, deep sound profiles, the split between the top and bottom housing materials may lead to variations in typing experience. The softness and sound-absorbing qualities of nylon and Gazzew blend plastics contribute to a similar overall sound profile, but users may notice differences in feel and sound distribution between the top and bottom of the switches. Ultimately, the choice between the Jammy and U4 switches may come down to personal preference in terms of typing feel and sound characteristics.
Weight
Comparing the actuation force and bottom out force of the HMX Jammy linear switch and the Gazzew U4 tactile switch reveals some interesting differences. The Jammy has a slightly higher actuation force of 57 grams compared to the U4's 45 grams, making it slightly heavier. However, both switches have a similar bottom out force, with the Jammy requiring 63 grams and the U4 requiring 62 grams. This means that while the Jammy may feel slightly heavier to press initially, the overall typing experience in terms of bottoming out is quite similar between the two switches. Those who prefer a lighter typing experience may lean towards the U4, while those who enjoy a bit more resistance when typing may opt for the Jammy. Ultimately, the weight of the switch will play a significant role in determining which one is the better fit for individual preferences.
Travel distance
The HMX Jammy linear switch has a travel distance of 3.7 mm, while the Gazzew U4 tactile switch has a travel distance of 3.6 mm. Both switches have relatively short travel distances compared to more traditional switches. The Jammy is slightly longer by 0.1 mm, but the difference is minimal and would likely not be noticeable to most users. Overall, both switches offer a quick and responsive typing experience, making them suitable for gaming or typing tasks that require speed. Ultimately, the decision between the two switches would likely come down to personal preference rather than the slight variation in travel distance.

Typing experience
When it comes to sound, the HMX Jammy linear switch is best described as having a softer and more muted sound due to its nylon housing, creating a typing experience that is both quiet and satisfying. On the other hand, the Gazzew U4 tactile switch is known for its whisper-quiet sound profile, making it ideal for those who prefer a more stealthy typing experience. The U4's low-pitched tone adds a unique depth to its sound, contributing to its overall quiet and pleasant typing experience.
Turning to the feel of the switches, the HMX Jammy linear switch offers a smooth and consistent typing experience with a medium weight that is comfortable for extended typing sessions. The Gazzew U4 tactile switch, on the other hand, provides a sharp and exhilarating tactile bump that adds a high level of feedback intensity to each keypress. The felt-like bottom-out sensation of the U4 further enhances the typing experience, creating a plush and satisfying feel with each keystroke.
Overall, the HMX Jammy linear switch and the Gazzew U4 tactile switch offer distinct typing experiences in terms of sound and feel. While the Jammy switch provides a quieter and more muted typing experience with a smooth linear feel, the U4 switch offers a sharp tactile feedback and a whisper-quiet sound profile. Both switches have their own unique characteristics that cater to different preferences, so choosing between the two will ultimately depend on your personal typing style and preferences.
Conclusion
In closing, when deciding between the HMX Jammy linear switch and the Gazzew U4 tactile switch, consider the following guidelines. Choose the Jammy linear switch if you prefer a medium-weight switch with a typing experience that is both muted and deeply satisfying. On the other hand, opt for the Gazzew U4 tactile switch if you enjoy a sharp and exhilarating tactile bump accompanied by an unexpectedly plush bottom-out sensation. The U4 also offers a whisper-quiet sound profile, making it a great choice for those who prefer a quieter typing experience. Ultimately, your decision should be based on whether you prioritize a softer typing experience with the Jammy or a tactile and quiet typing experience with the U4.
